An object-oriented database (OODB) is a type of DBMS that is designed to store and manage data using object-oriented principles. Learn more about it through this blog.
is a straightforward approach to concurrency control in a database management system (DBMS). It aims to provide a simple mechanism for coordinating access to shared data items by transactions. This type of lock protocol may lack some of the advanced features and optimizations found in more complex...
there could arise many problems if the access control is not done properly. There are some important mechanisms to which access control can be maintained. Earlier we talked about theoretical concepts like serializability, but the practical concept of this can be implemented by usingLocksandTimestamps...
In a multiprogramming environment where multiple transactions can be executed simultaneously, it is highly important to control the concurrency of transactions. We have concurrency control protocols to ensure atomicity, isolation, and serializability of concurrent transactions. Concurrency control protocols can...
